Bid Sniper Script

Need a simple bid sniper script like [url removed, login to view] does not need to be fancy. You can view the sites I will be integrating it with at [url removed, login to view] , view them sites at the top image links ( webs, pay, pic, post, mind, play) as you can see the simplicity of the scripts like the personpic site and the personmind site, thats really as complex as I need the personbid site script to be, nothing fancy, just meat and potatoes scripting. The personpost sites script is not worth anything, no one would really find that useful. I want to replace that one in the network with [url removed, login to view] and need a bid sniper type script that will work with users being able to signup for free, allowing free accounts to only have one snipe active at a time, with an option to signup as a paid member who can have multiple bid snipes active at a time, also there should be an upgrade feature to allow free members to upgrade at any time to paid. I need the script to use header and footer files so that every page can look just like the other sites in the [url removed, login to view] network of sites. I will pay with GAF escrow. The script would need to be setup and testable on my site so I can test its functionality before the escrow payment is released. It only needs to work with eBay auctions and it needs to work consistently.
